Button background color based on HVAC fan mode?

Configuration Frontend
1

So I would like to change the background of my button when a certain HVAC fan mode is active/selected (auto / always on). Right now I have two buttons, one for auto and one for on. The perform like they should, switching the HVAC fan mode.

I want them to mimic the buttons above. So when “HVAC Auto” is selected the back ground is turned blue and when its switched to “Fan On” the background goes to default and “HVAC Fan On” is turned blue.

Any help or ideas would be much appreciated.
